Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing illustrated embodiment.
Embodiment one：
With reference to shown in Fig. 1 and Fig. 8, the invention provides a kind of many level damping classification surrender metal dampers, it is set
In building structure, the non-compliant section 4 using the coupling beam of Coupled Shear Wall 5 is for replacing part coupling beam to be tied as building in the present embodiment
The applicating example of structure, it includes two ring dampers being set with exterior and interior axle sleeves, described two ring dampers small one and large one,
Less inner ring damper 2 is enclosed on the inside of larger outer shroud damper 1, the planar section of two ring damper left and right sides
Between be provided with connection backing plate 3, described two ring dampers are directly connected with the built-in fitting (i.e. non-compliant section 4) of coupling beam.
Specifically, with reference to shown in Fig. 2 to Fig. 4, each ring damper includes the segmental arc at two ends and is connected to
Interlude between segmental arc described in two ends, the interlude provided with expand connecting plate 99, the connection backing plate 3 be clamped and connected in
Between adjacent two pieces of expansion connecting plates 99 of inside and outside two ring dampers.Every piece of described expands opens on connecting plate 99
Provided with some screws 98, the expansion connecting plate 99 is connected with the bolt 7 of connection backing plate 3, and many level damping classifications are bent
Take the non-compliant section 4 that metal damper coordinates high-strength bolt to be connected to the coupling beam by the connection backing plate 3, the non-compliant
Section 4 is embedded in the Coupled Shear Wall 5 in advance.
Preferably, the ring damper is formed by the cutting of block of metal plate or polylith metal plate weld is spliced.Institute
The link position for stating segmental arc and the interlude smoothly transits, to prevent stress concentration.Two described annular dampers
Device is made of Q235 steel or Low Yield Point Steel, and inside and outside two ring dampers are made up of same material or different materials,
There is different yield displacements respectively under inside and outside two ring damper different anti-seismic levels.
Analyzed respectively by finite element modelling and calculate maximum of the inside and outside ring damper when designing displacement laterally
Deflection, the thickness of the connection backing plate 3 is more than the maximum lateral deformation amount.Wherein, design displacement refers to determine during design
Maximum relative displacement of the damper in macroseism, yield displacement refers to that the inner ring and outer rings of damper initially enter surrender respectively
Corresponding displacement during state.In the design process of damper, according to different target of the structure under different fortification earthquakes
Displacement demand, is calculated by the displacement of targets demand of structure and obtains relative deformation of the damper under different fortifications, Ran Houtong
Cross finite element modelling and experiment determines the size of inner ring and outer rings damper.
When practical application, many level damping classification surrender metal dampers can be applied to a variety of building structure rings
Under border, for example, between Coupled Shear Wall 5.Specifically, there is building between the Coupled Shear Wall 5 or above the coupling beam
Plate 6, the design displacement is less than the vertical clearance between many level damping classification surrender metal dampers and the floor 6
From.The non-compliant section 4 of the coupling beam is preferably designed to non-uniform beam, the termination size of non-uniform beam and the middle part size phase of outer shroud
Closely.
Also many level damping classification surrender metal damper branch can be located at the interlayer of frame structure and then is classified and bent
Metal damper, can be specifically supported in frame structure by clothes power consumption by support or wall.(not shown)
When flexural deformation, in small shake or middle shake, the less surrender of inner ring damper 2 power consumption, the larger outer shroud in outside
Shape damper 1 is in elasticity, and in big shake, inside and outside two ring dampers surrender power consumption together.
During construction, such as Fig. 8, this many level damping classification surrender metal damper assembled can be completed in advance, metal damper
Connection backing plate 3 at be connected by high-strength bolt with the built-in fitting (i.e. non-compliant section 4) in coupling beam.
ABAQUS numerical simulations have been carried out to this example, referring to accompanying drawing 5, it can be found that the present invention is under the effect of middle earthquake magnitude,
Inner ring damper 2 enters plasticity and consumed energy, and outer shroud damper 1 is in elastic stage；Referring to accompanying drawing 6, it can be found that in big shake effect
Under, two ring dampers enter plasticity and consumed energy together；Fig. 7 is the hysteresis loop figure of the present invention, and this hair is can be found that from figure
Typical three linear character, i.e. starting stage elasticity is presented in bright skeleton curve, and then inner ring damper 2 is surrendered, last outer shroud
Damper 1 is surrendered, and illustrates that expected design is fully achieved in the present invention, and the classification surrender shaken and shaken greatly can meet simultaneously in is required.
Embodiment two (not shown)：
On the basis of embodiment one, the present invention also provides a kind of many level damping classification surrender metal dampers, compares
In embodiment one, difference is, have in the present embodiment it is outer in three ring dampers, and between adjacent annular damper
Still it is connected by connection backing plate.And then, in application implementation, the ring damper in inner ring surrenders power consumption in small shake
(i.e. small shake when middle ring and outer shroud keep elasticity), just surrender power consumption is (interior during middle shake in middle earthquake magnitude for the ring damper of middle ring
Ring and middle ring all surrender power consumption, and outer shroud keeps elasticity), the ring damper of outer shroud just surrenders power consumption in big shake (during big shake
Inner ring, middle ring and outer shroud all surrender power consumption).Other structures are substantially identical with embodiment one, and just no longer this adds to repeat.
Complete after above-mentioned implementation process, following characteristics of the present invention should be able to be embodied：
The present invention can be used in Coupled Shear Wall or frame structure, can realize that classification is bent under different anti-seismic fortification
